A gold color metal and enamel device 1 1/8 inches (2.86cm) in height overall consisting of a gold balance standing in a black area above two gold steps and between two gold columns each charged with a green sword point up and their capitols joined by a gold arch indented at top and each charged with a green five-pointed star; the whole surrounded by a curving green scroll inscribed in gold with the words "JUSTICE" at the top and "WILL PREVAIL" at the bottom.
Gold and green are the colors of the Military Police Corps. The columns and arch were suggested by the seal of the state of Georgia, the Group's home state. The scales represent equal justice and the swords on either side signify military security. The three stars on the arch above denote legal authority and refer as well to the unit's numerical designation. The darkness in the center represents the mystery surrounding crime which must be cleared up through criminal investigation, a major part of the mission of the 3d Military Police Group.
The distinctive unit insignia was approved on 6 Mar 1969.
